SPECIFICATION forming part of Letters Ifatent No. 630,184, dated August 1, 1899.

Application filed August 6, 1898. $eria1llo. 687,948. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE KISSAM Cooxn, a citizen of the United States, residing at New York, (Jamaica,) in the borough of Queens, State of New York, have invented a certain new and useful Improvement in Self-Closing Faucets, of which the following is a specification.

This invention pertains to improvements in that class of faucets known as self-closing to secure the best results in a simple and reliable manner 5 and it consists in the construction and arrangement of parts, fully set forth below and pointed out in the claims.

The accompanying drawings form a part of this specification and represent what 1 consider the best means of carrying out the invention.

Figure l is a general side View of the faucet. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a cross-section on the line 2 2 in Figs. 1 and 2; and Fig. 4, a crosssection on the line 4: 4 in Figs. 1 and 2, viewed from the left.

Similar letters of reference apply to all the drawings.

. A is the body of the faucet, which is provided with a peculiar water-course through it.

B is a hollow stem or supply connection which is removably attached to the body A by screwing firmly into the same and is provided with a threaded end and nut and elastic washers.

A is the discharge-nozzle, formed integral with the body. 7 The Waterway in the body of the faucet A is of different diameters, the part a being of less diameter than the part Cb and the part a being less than either. The part a connects with the opening through the dischargenozzle A. A hollow extension A from the body of the faucet connects with the interior a by a small orifice a, through which plays a rod D, screwed tightly into a puppet-valve E. A short length of tubing F, made of the best vulcanized rubber, is tightly fitted in the. portion a of the faucet-body, abutting against the offset made by the smaller portion a forming a tubular flexible valve-seat open at both ends and extending a short distance into the larger portion a, which latter is tapered, leaving a conical space b around the rim of the rubber seat, adapted to match the seat yieldingly and tightly to the valve.

The valve-rod D is fixed at its opposite end to a push-button D, on which is cast a hollow shell D having a longitudinal ridge or feather D along its lower side, which telescopes with the extension A and moves loosely therein, the latter having an internal groove M, which receives the feather D and allows the rod and valve to move endwise, but forbids their revolving.

Surrounding and fitting snugly on the valve-rod D is a leather Washer G, matching against the surface around the hole a. Press ing against the leather washer is a metal washer l-I, having a central opening it slightly larger than the valve-rod D, which passes through it. A spiral spring I encircles the valve-rod, one end abutting upon the metal Washer H and the other end pressing against the interior of the push-button D. The gentle force of this spring urges the valve E to its seat and the telescoping construction hides the spring from view and protects and guides the parts.

I provide a finger clutch or hearing A con- .sisting of an enlarged outer diameter of the body of the faucet at the connection of the discharge-nozzle A with the faucet-body A, to form an abutment for the fingers in operating the push-button.

It will be seen that when the push-button D is pressed the spiral spring I is compressed and the valve-rod D is thrown inward, carrying with it the valve E and removing it from the valve-seat F, thus allowing a free passage for a flow of liquid through the waterway, past the valve E, and out through the discharge-nozzle A. When the pressure of the thumb on the push-button is relaxed, the spring I presses the parts back to the original position. In the act of closing, the valve E is pressed in to the flexible val ve-seat F, distending that end and forcing it outward and against the conical interior of the body of the faucet, thus seating the valve E in a watertight seat of the same configuration as the outer form of the valve E. The flexible packing-washer G is held firmly in position around the Valve-rod D in the hollow extension A by the pressure of the spiral spring I on the metal washer H. This packs the leather washer G against the metal around the valve-rod and against the metal around the orifice a, forming a water-tight joint. This is especially important in case a pipe or filter is attached to the nozzle, so as to create a pressure of the fluid in this part of the interior. The metal washer H assists in holding the flexible washer in place and in guiding the valve-rod D and valve E centrally when in motion. A clamping-nut C is shown in Fig. 1 screwed to the stem B to attach the stem firmly to the usual opening in a liquid-receptacle. A plain stem can be substituted when it is required to solder the same to a can or other vessel or to plumbing-work.

The removable stem B allows the assembling of the interior parts of the faucet, which could not be otherwise reached for that purpose when constructed as shown.

The removable stem can be attached to a receptacle without the body of the faucet being attached to it, thus securing a saving in sizefof package, freight, &c., and damage to the faucet in transit.

The valve E and valve-seat F are construct ed with a view to prevent leaking and to secure a perfect seating of the valve in its fiexi bl'e seat with a comparatively weak spring and without the need of using undue force to that end. The pressure of the liquid upon the valve E assists materially in seating it securely. This result is secured by the construction and arrangement of the parts as hereinbefore described.

The fin or ridge projection D in combination with the groove a, prevents the parts from becoming injured or detached when the faucetjs used and operated by unskilled operators.

The projecting portion of the faucet-body at A forms a convenient and needed clutch and rest for the fingers when operating the push-button D.

I claim as my invention- 1. In a faucet, a body portion having the large passage a, the smaller passage a and the still smaller passage a in line as shown, a "seat F of yielding material matched in the intermediate size a and resting against an offset, a valve of rigid material adapted to bear within and expand a portion of the seating in the larger portion a, and valve-operating means D D I, substantially as herein specified.

2. In a faucet, a body portion having the parts a, 00*, of the waterway of varying diameters and presenting the rounded offset, a cylindrical seat of yielding material within the part a and extending freely .within the part a, in combination with a valve of rigid material adapted to bear within and expand the free portion of the seating, and valve-opcrating means, substantially as herein specified.

3. In a self-closing faucet, the combination with a body portion having an integral tubular projection communicating with the noz-. zle-passage and provided with an internal longitudinal groove, ofa valve-operating button having a tubular extension playing within said projection and provided with a spline engaging the groove thereof, an interposed expansion-spring within both the projection and the'extension, a rod connected to the button, extending through the projection across the nozzle into the waterway beyond and carrying a valve thereat, substantially as specified.

4. In a faucet, the combination with the body having the large rear and smaller intermediate and nozzle portions, of a spring-actuated rod having its threaded end extending to the larger rear portion, a valve on said end, a tubular seat F of yielding material, cooperating with said valve, and a removable stem adapted for detachment from the larger end of the body, substantially as herein specified.

5. In a self-closing faucet, the combination with a body portion having an integral tubular projection communicating with the nozzle passage through an opening Ctill a partition, said projection being provided with an internal longitudinal groove, a yielding washer G within the projection seated against the partition and faced by a rigid washer H, having a larger perforation, a valve-operating button having a tubular extension playing within said projection and having a spline engaging the groove thereof, an interposed expansionspring within both the projection and the extension, a rod connected to the button, extending through the projecting washer and partition across the nozzle into the waterway beyond and carrying a valve thereat,substantially as herein specified.

6. In a self-closin g faucet, the combination with the body portion having an integral tubular projection communicating with the nozzle-passage, the external portion of the arch of which projects to constitute a finger rest or bearing, said tubular projection being provided with an internal longitudinal groove, of a valve-operating button having a tubular extension playing within said projection and having a spline engaging the groove thereof, an independent expanding-spring within both the tubular projection and the extension, a rod connected to the button extending through the projection across the nozzle into the waterway beyond and carrying a valve thereat, substantially as specified.

7. In a self-closing faucet, the body or casing A, having a nozzle A and provided with a tubular projection A grooved as described, a button having a tubular extension carrying a rib playing in said groove, an interposed expansion-spring, a cylindrical seating of flexible material, a valve-rod extending from the button through an opening h, and carrying a valve adapted to enter and expand the elastic cylindrical seating within a graduallyenlarged portion of the body, rigid and yielding washers H, I, located contiguous to the opening it, in combination with an independent section B, removably attached to the larger end, all combined and arranged to serve substantially as herein specified.

In testimony that I claim the invention above set forth I affix my signatnre'in presence of two witnesses.
